Drying, fish

Seafood. Sorbates are used to extend the shelf life of many seafood products, both fresh and processed (103,104). For smoked or dried fish, an instantaneous dip in 5 wt % potassium sorbate or a 10-minute dip in 1.0 wt % potassium sorbate prior to drying or smoking inhibits the development of yeast and mold (105,106). For fresh fish, sorbates can be incorporated at approximately 0.5 wt % into the ice, refrigerated seawater, or ice-water slush in...

Many food raw materials and produets have to be treated with chemical insecticides to prevent losses due to damage eaused by fly larvae, beetles, and other inseets. This applies to, for example, dried fish, dried fruits, raisins, almonds, nuts, eoeoa beans, and grain.

Dried fruits, vegetables, and nuts, as well as dried fish, an important source of protein in many developing countries, are also good candidates for radiation disinfestation. Application of 0.2-0.7 kGy doses, if they have been suitably packaged to prevent reinfestation, can eliminate the insect problem from these products that cannot be elfectively disinfested by either chemical or physical means other than irradiation.

Samples of freeze-dried fish tissues are extracted with 25% tetramethy-lammonium hydroxide using a microwave digester. After extraction, the pH is adjusted to 4 with acetic acid buffer. A 1% solution of NaBEt4 is added, with some hexane. The solution is shaken for 5 minutes. A fresh portion of NaBEt4 is added, the shaking is repeated, and finally, a third portion is added and allowed to react. The sample is centrifuged and an aliquot of the supernatant hexane is taken for injection into the GC [132],...

The major emphasis should be the prevention of rickets by providing adequate calcium and vitamin D in the diet, particularly if exposure to sunlight is restricted. One teaspoon (4mL) of cod-liver oil provides 360 IU of vitamin D. In developing countries where dairy products are prohibitively expensive, local foods such as dried fish containing small soft bones can add to the calcium intake (Larsen et al., 2000). 

The final dry fish meal may not contain more than 1 percent oil by weight. The weight ratio of solvent to insolubles at the end of each cooker batch must be 3 1. The fish-meal filter cake must be washed with a weight of solvent at least equal to the weight of the dry fish meal in order to ensure adequate oil removal. 

The solid material remaining after filtration contains 1.0 lb of solvent per pound of dry fish meal. 

Dried fish. Cut samples into small pieces, mix, reduce by quartering to ca. lOOg, and grind as finely as possible. 

Drying was one such method and pemmican, cakes made from dried meat and berries, was a Native American staple for hundreds of years. In ancient Egypt, people used the power of the sun to dry their fish and poultry, and the Babylonians created a paste from pounded dried fish that they used to season their stews. Such dried foods could be stored indefinitely. 

Although the protein component is needed for emulsification, sugars are often added to the mix. The oxidative stability of spray-dried fish oil emulsions was found to increase with increasing dextrose equivalence (DE) of the carbohydrate used in...
